A heat map is a graphical representation of two dimensional data (X, Y and Value) on a two dimensional surface by using colors. On a map a heat map is a representation of density of latitude and longitude points on a map. HeatmapAPI lets you creates heat map images you can overlay on your maps in your software.
Jeffrey Barke has written up a tutorial detailing how to create a density map with Prototype, the Google Maps API and the HeatMapAPI.
How do Heat Maps Help?
Heat maps allow users quickly visualize density. Most maps you see, show points or themed polygons, but being able to understand the density of those points makes it much easier to see, especially when using colors with a heat map.
Create Your Own Heat Maps
We give you an API that enables you to create your own heat maps on your maps, in your application. We offer a limited but free API you can use, or you can upgrade for unlimited data points or optionally run the API on your server.
Google Example with Javascript (less than 60 points) (Live)
